在天文学上,star指的是“恒星”。太阳系(solar system)只有一个star(恒星),会发光、发热,那就是太阳。 Planets(行星) 金星则是 planet(行星),不发光,也不发热,在轨道上环绕太阳运行(orbit)。 ORBIT:To move in a path around another object, such as ...
3.Outer Solar System The outer region of the Solar System is home to thegiant planetsandtheir large moons. The centaurs and manyshort-period cometsalso orbit in this region. Due to their greater distance from the Sun, the solid objects in the outer Solar System contain ahigher proportion of...

There are eight planets in our Solar System that orbit around the Sun. In order, going from the closest planet to the Sun, to the one that is farthest away, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. All of the planets and the Sun are round, like ...
The Solar System Our local neighborhood in space is called the solar system. At its heart is the Sun, an ordinary star that is so close it floods our planet with light. Trapped in its orbit by gravity are Earth and seven other planets, their many moons, and millions of comets and aster...
Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust
planets have moons that orbit them in the same way that ourMoon orbits the Earth.Asteroids(小行星)were formed(构成)along with the restof the Solar System around 5,000 million years ago.They orbit theSun like the planets.方练有所得——学习能力构建1.How many planets are there orbiting the...
The mapping is based on the approximation that perturbations to the test particle orbit are localized near conjunction with the planet. We use the mapping to confirm Wisdom's result that initially circular test particle orbits are chaotic when |a − 1p|/ap≲ μ23, where μ is the planet...
Solar System Planet Facts for Kids Our solar system consists of eight planets which all orbit around our home star, the Sun. In the image is Jupiter and one of the moons - image taken by the Juno space craft, a NASA space mission
but then be perturbed by passing stars and the galactic tides.[5] As they come into or leave the inner Solar System they may have their orbit changed by the planets, or alternatively be ejected from the Solar System.[5] It is also possible they may collide with the Sun or a planet.[...
